the turbos waste gate on My factory stock 01 ram Diesel 3500 with an auto transmission, is seized, or so the shop says. The truck has 112000 original miles, so it has sat around, the truck starts and accelerates smoothly, but when climbing hills, it looses power. The shop has checked the fuel system and other checks and has determined that the turbos waste gate is seized up. The over boost faults are also logged.The turbo is a holeset. My question is, can the waste gate be replaced? our is a new turbo in order?
